The word "reincarnation" derives from Latin, literally meaning, "entering the flesh again". The Greek equivalent metempsychosis (μετεμψύχωσις) derives from meta (change) and empsykhoun (to put a soul into),[12] a term attributed to Pythagoras.[13] An alternate term is transmigration implying migration from one life (body) to another.[14] Reincarnation refers to the belief that an aspect of every human being (or all living beings in some cultures) continues to exist after death, this aspect may be the soul or mind or consciousness or something transcendent which is reborn in an interconnected cycle of existence; the transmigration belief varies by culture, and is envisioned to be in the form of a newly born human being, or animal, or plant, or spirit, or as a being in some other non-human realm of existence.[15][16][17] The term has been used by modern philosophers such as Kurt Gödel[18] and has entered the English language. Another Greek term sometimes used synonymously is palingenesis, "being born again".[19]

Rebirth is a key concept found in major Indian religions, and discussed with various terms. Punarjanman (Sanskrit: पुनर्जन्मन्) means "rebirth, transmigration".[20][21] Reincarnation is discussed in the ancient Sanskrit texts of Buddhism, Hinduism, and Jainism, with many alternate terms such as punarāvṛtti (पुनरावृत्ति), punarājāti (पुनराजाति), punarjīvātu (पुनर्जीवातु), punarbhava (पुनर्भव), āgati-gati (आगति-गति, common in Buddhist Pali text), nibbattin (निब्बत्तिन्), upapatti (उपपत्ति), and uppajjana (उप्पज्जन).[20][22] These religions believe that this reincarnation is cyclic and an endless Saṃsāra, unless one gains spiritual insights that ends this cycle leading to liberation.[2][3] The reincarnation concept is considered in Indian religions as a step that starts each "cycle of aimless drifting, wandering or mundane existence",[2] but one that is an opportunity to seek spiritual liberation through ethical living and a variety of meditative, yogic (marga), or other spiritual practices.[23][24] They consider the release from the cycle of reincarnations as the ultimate spiritual goal, and call the liberation by terms such as moksha, nirvana, mukti and kaivalya.[25][26] However, the Buddhist, Hindu and Jain traditions have differed, since ancient times, in their assumptions and in their details on what reincarnates, how reincarnation occurs and what leads to liberation.[27][28]

Gilgul, Gilgul neshamot or Gilgulei Ha Neshamot (Heb. גלגול הנשמות) refers to the concept of reincarnation in KabbalisticJudaism, found in much Yiddish literature among Ashkenazi Jews. Gilgul means "cycle" and neshamot is "souls". Version of Kabbalistic reincarnation says that humans reincarnate only to humans and to the same sex only: men to men, women to women.[citation needed]

The origins of the notion of reincarnation are obscure.[29] Discussion of the subject appears in the philosophical traditions of India. The Greek Pre-Socratics discussed reincarnation, and the Celtic Druids are also reported to have taught a doctrine of reincarnation.[30]

The ideas associated with reincarnation may have arisen independently in different regions, or they might have spread as a result of cultural contact. Proponents of cultural transmission have looked for links between Iron Age Celtic, Greek and Vedic philosophy and religion,[31] some[who?] even suggesting that belief in reincarnation was present in Proto-Indo-European religion.[dubious– discuss][32] In ancient European, Iranian and Indian agricultural cultures, the life cycles of birth, death, and rebirth were recognized as a replica of natural agricultural cycles.[33]

The idea of reincarnation has early roots in the Vedic period (c. 1500 – c. 500 BCE), predating the Buddha and the Mahavira.[34] The concepts of the cycle of birth and death, samsara, and liberation partly derive from ascetic traditions that arose in India around the middle of the first millennium BCE.[35] Though no direct evidence of this has been found, the tribes of the Ganges valley or the Dravidian traditions of South India have been proposed as another early source of reincarnation beliefs.[36]

Hinduism's Rigveda makes references to reincarnation in the Brahmanas layer.[37][38][39] Though these early textual layers of the Vedas, from 2nd millennium BCE, mention and anticipate the doctrine of Karma and rebirth, the idea is not fully developed.[40][41][42] It is in the early Upanishads, which are pre-Buddha and pre-Mahavira, where these ideas are more explicitly developed in a general way.[40] Detailed descriptions first appear around the mid 1st millennium BCE in diverse traditions, including Buddhism, Jainism and various schools of Hindu philosophy, each of which gave unique expression to the general principle.[3]

The texts of ancient Jainism that have survived into the modern era are post-Mahavira, likely from the last centuries of the 1st millennium BCE, and extensively mention rebirth and karma doctrines.[43][44] The Jaina philosophy assumes that the soul (Jiva in Jainism, Atman in Hinduism) exists and is eternal, passing through cycles of transmigration and rebirth.[45] After death, reincarnation into a new body is asserted to be instantaneous in early Jaina texts.[44] Depending upon the accumulated karma, rebirth occurs into a higher or lower bodily form, either in heaven or hell or earthly realm.[46][47] No bodily form is permanent: everyone dies and reincarnates further. Liberation (kevalya) from reincarnation is possible, however, through removing and ending karmic accumulations to one's soul.[48] From the early stages of Jainism on, a human being was considered the highest mortal being, with the potential to achieve liberation, particularly through asceticism.[49][50][51]

The early Buddhist texts discuss rebirth as part of the doctrine of Saṃsāra. This asserts that the nature of existence is a "suffering-laden cycle of life, death, and rebirth, without beginning or end".[52][53] Also referred to as the wheel of existence (Bhavacakra), it is often mentioned in Buddhist texts with the term punarbhava (rebirth, re-becoming). Liberation from this cycle of existence, Nirvana, is the foundation and the most important purpose of Buddhism.[52][54][55] Buddhist texts also assert that an enlightened person knows his previous births, a knowledge achieved through high levels of meditative concentration.[56] Tibetan Buddhism discusses death, bardo (an intermediate state), and rebirth in texts such as the The Tibetan Book of the Dead. While Nirvana is taught as the ultimate goal in Buddhism, the vast majority of contemporary lay Buddhists focus on accumulating good karma and acquiring merit to achieve a better reincarnation in the next life.[57][58]

In early Buddhist traditions, Saṃsāra cosmology consisted of five realms through which the wheel of existence cycled.[52] This included hells (niraya), hungry ghosts (pretas), animals (tiryak), humans (manushya), and gods (devas, heavenly).[52][53][59] In latter Buddhist traditions, this list grew to a list of six realms of rebirth, adding demi-gods (asuras).[52][60]

The earliest layers of Vedic text incorporate the concept of life, followed by an afterlife in heaven and hell based on cumulative virtues (merit) or vices (demerit).[61] However, the ancient Vedic Rishis challenged this idea of afterlife as simplistic, because people do not live an equally moral or immoral life. Between generally virtuous lives, some are more virtuous; while evil too has degrees, and the texts assert that it would be unfair for people, with varying degrees of virtue or vices, to end up in heaven or hell, in "either or" and disproportionate manner irrespective of how virtuous or vicious their lives were.[62][63][64] They introduced the idea of an afterlife in heaven or hell in proportion to one's merit, and when this runs out, one returns and is reborn.[65][66][67] This idea appears in ancient and medieval texts, as the cycle of life, death, rebirth and redeath, such as section 6:31 of the Mahabharata and section 6.10 of Devi Bhagavata Purana.[62][68][69]

Buddhism, Hinduism and Jainism disagree in their assumptions and theories about rebirth. Hinduism relies on its foundational assumption that "soul, Self exists" (Atman, attā), in contrast to Buddhist assumption that there is "no soul, no Self" (Anatta, anatman).[74][75][76] Hindu traditions consider soul to be the unchanging eternal essence of a living being, and what journeys across reincarnations until it attains self-knowledge.[77][78][79] Buddhism, in contrast, asserts a rebirth theory without a Self, and considers realization of non-Self or Emptiness as Nirvana (nibbana). Thus Buddhism and Hinduism have a very different view on whether a self or soul exists, which impacts the details of their respective rebirth theories.[80][81][82]

The reincarnation doctrine in Jainism differs from those in Buddhism, even though both are non-theistic Sramana traditions.[83][84] Jainism, in contrast to Buddhism, accepts the foundational assumption that soul exists (Jiva) and asserts this soul is involved in the rebirth mechanism.[85] Further, Jainism considers asceticism as an important means to spiritual liberation that ends all reincarnation, while Buddhism does not.[83][86][87]

Early Greek discussion of the concept likewise dates to the 6th century BCE. An early Greek thinker known to have considered rebirth is Pherecydes of Syros (fl. 540 BCE).[88] His younger contemporary Pythagoras (c. 570–c. 495 BCE[89]), its first famous exponent, instituted societies for its diffusion. Plato (428/427–348/347 BCE) presented accounts of reincarnation in his works, particularly the Myth of Er.

Authorities have not agreed on how the notion arose in Greece: sometimes Pythagoras is said to have been Pherecydes' pupil, sometimes to have introduced it with the doctrine of Orphism, a Thracian religion that was to be important in the diffusion of reincarnation, or else to have brought the teaching from India. In Phaedo, Plato makes his teacher Socrates, prior to his death, state: "I am confident that there truly is such a thing as living again, and that the living spring from the dead." However Xenophon does not mention Socrates as believing in reincarnation and Plato may have systematised Socrates' thought with concepts he took directly from Pythagoreanism or Orphism.

The Orphic religion, which taught reincarnation, about the 6th century BC, organized itself into mystery schools at Eleusis and elsewhere, and produced a copious literature.[90][91][92]Orpheus, its legendary founder, is said to have taught that the immortal soul aspires to freedom while the body holds it prisoner. The wheel of birth revolves, the soul alternates between freedom and captivity round the wide circle of necessity. Orpheus proclaimed the need of the grace of the gods, Dionysus in particular, and of self-purification until the soul has completed the spiral ascent of destiny to live for ever.

An association between Pythagorean philosophy and reincarnation was routinely accepted throughout antiquity. In the Republic Plato makes Socrates tell how Er, the son of Armenius, miraculously returned to life on the twelfth day after death and recounted the secrets of the other world. There are myths and theories to the same effect in other dialogues, in the Chariot allegory of the Phaedrus, in the Meno, Timaeus and Laws. The soul, once separated from the body, spends an indeterminate amount of time in "formland" (see The Allegory of the Cave in The Republic) and then assumes another body.

In later Greek literature the doctrine is mentioned in a fragment of Menander[93] and satirized by Lucian.[94] In Roman literature it is found as early as Ennius,[95] who, in a lost passage of his Annals, told how he had seen Homer in a dream, who had assured him that the same soul which had animated both the poets had once belonged to a peacock. Persius in his satires (vi. 9) laughs at this, it is referred to also by Lucretius[96] and Horace.[97]

In Greco-Roman thought, the concept of metempsychosis disappeared with the rise of Early Christianity, reincarnation being incompatible with the Christian core doctrine of salvation of the faithful after death. It has been suggested that some of the early Church Fathers, especially Origen still entertained a belief in the possibility of reincarnation, but evidence is tenuous, and the writings of Origen as they have come down to us speak explicitly against it.[99]

In the third Christian century Manichaeism spread both east and west from Babylonia, then within the Sassanid Empire, where its founder Mani lived about 216–276. Manichaean monasteries existed in Rome in 312 AD. Noting Mani's early travels to the Kushan Empire and other Buddhist influences in Manichaeism, Richard Foltz[101] attributes Mani's teaching of reincarnation to Buddhist influence. However the inter-relation of Manicheanism, Orphism, Gnosticism and neo-Platonism is far from clear.

The Pythagorean doctrine prevails among the Gauls' teaching that the souls of men are immortal, and that after a fixed number of years they will enter into another body.

Julius Caesar recorded that the druids of Gaul, Britain and Ireland had metempsychosis as one of their core doctrines:[102]

The principal point of their doctrine is that the soul does not die and that after death it passes from one body into another... the main object of all education is, in their opinion, to imbue their scholars with a firm belief in the indestructibility of the human soul, which, according to their belief, merely passes at death from one tenement to another; for by such doctrine alone, they say, which robs death of all its terrors, can the highest form of human courage be developed.

In Judaism, the Zohar, first published in the 13th century, discusses reincarnation at length, especially in the Torah portion "Balak." The most comprehensive kabbalistic work on reincarnation, Shaar HaGilgulim,[103][104] was written by Rabbi Chaim Vital, based on the teachings of his mentor, the 16th century kabbalist Rabbi Isaac Luria, who was said to know the past lives of each person through his semi-prophetic abilities. The 18th century Lithuanian master scholar and kabbalist, Rabbi Elijah, known as the Vilna Gaon (Elijah of Vilna), authored a commentary on the biblical Book of Jonah as an allegory of reincarnation.

Taoist documents from as early as the Han Dynasty claimed that Lao Tzu appeared on earth as different persons in different times beginning in the legendary era of Three Sovereigns and Five Emperors. The (ca. 3rd century BC) Chuang Tzu states: "Birth is not a beginning; death is not an end. There is existence without limitation; there is continuity without a starting-point. Existence without limitation is Space. Continuity without a starting point is Time. There is birth, there is death, there is issuing forth, there is entering in."[107]

Around the 11–12th century several reincarnationist movements were persecuted as heresies, through the establishment of the Inquisition in the Latin west. These included the Cathar, Paterene or Albigensian church of western Europe, the Paulician movement, which arose in Armenia,[108] and the Bogomils in Bulgaria.[109]

Christian sects such as the Bogomils and the Cathars, who professed reincarnation and other gnostic beliefs, were referred to as "Manichean", and are today sometimes described by scholars as "Neo-Manichean".[110] As there is no known Manichaean mythology or terminology in the writings of these groups there has been some dispute among historians as to whether these groups truly were descendants of Manichaeism.[111]

The belief in reincarnation may have been commonplace among the Norse since the annotator of the Poetic Edda wrote that people formerly used to believe in it:

Sigrun was early dead of sorrow and grief. It was believed in olden times that people were born again, but that is now called old wives' folly. Of Helgi and Sigrun it is said that they were born again; he became Helgi Haddingjaskati, and she Kara the daughter of Halfdan, as is told in the Lay of Kara, and she was a Valkyrie.[112]

While reincarnation has been a matter of faith in some communities from an early date it has also frequently been argued for on principle, as Plato does when he argues that the number of souls must be finite because souls are indestructible,[113]Benjamin Franklin held a similar view.[114] Sometimes such convictions, as in Socrates' case, arise from a more general personal faith, at other times from anecdotal evidence such as Plato makes Socrates offer in the Myth of Er.

During the Renaissance translations of Plato, the Hermetica and other works fostered new European interest in reincarnation. Marsilio Ficino[115] argued that Plato's references to reincarnation were intended allegorically, Shakespeare made fun[116] but Giordano Bruno was burned at the stake by authorities after being found guilty of heresy by the Roman Inquisition for his teachings.[117] But the Greek philosophical works remained available and, particularly in north Europe, were discussed by groups such as the Cambridge Platonists.

Théodore Flournoy was among the first to study a claim of past-life recall in the course of his investigation of the medium Hélène Smith, published in 1900, in which he defined the possibility of cryptomnesia in such accounts.[124]Carl Gustav Jung, like Flournoy based in Switzerland, also emulated him in his thesis based on a study of cryptomnesia in psychism. Later Jung would emphasise the importance of the persistence of memory and ego in psychological study of reincarnation: "This concept of rebirth necessarily implies the continuity of personality... (that) one is able, at least potentially, to remember that one has lived through previous existences, and that these existences were one's own...."[121]Hypnosis, used in psychoanalysis for retrieving forgotten memories, was eventually tried as a means of studying the phenomenon of past life recall.

Stevenson claimed there were a handful of cases that suggested evidence of xenoglossy. These included two where a subject under hypnosis could allegedly converse with people speaking the foreign language, instead of merely being able to recite foreign words. Sarah Thomason, a linguist at the University of Michigan, reanalyzed these cases, concluding that "the linguistic evidence is too weak to provide support for the claims of xenoglossy."[132]

Ian Wilson argued that a large number of Stevenson’s cases consisted of poor children remembering wealthy lives or belonging to a higher caste. He speculated that such cases may represent a scheme to obtain money from the family of the alleged former incarnation.[133] The philosopher Keith Augustine has written "the vast majority of Stevenson's cases come from countries where a religious belief in reincarnation is strong, and rarely elsewhere, seems to indicate that cultural conditioning (rather than reincarnation) generates claims of spontaneous past-life memories."[134] According to the research of Robert Baker many of the alleged past-life experiences investigated by Stevenson and other parapsychologists can be explained in terms of known psychological factors. Baker has written that recalling past lives is a mixture of cryptomnesia and confabulation.[135] The philosopher Paul Edwards noted that reincarnation invokes assumptions and is inconsistent with modern science.[136]

Objections to claims of reincarnation include the facts that the vast majority of people do not remember previous lives and there is no mechanism known to modern science that would enable a personality to survive death and travel to another body, barring the idea of biocentrism. Researchers such as Stevenson have acknowledged these limitations.[137]

The 14th Dalai Lama has stated his belief that it would be difficult for science to disprove reincarnation.

Recent studies have indicated that some Westerners accept the idea of reincarnation[11] including certain contemporary people who were to Catholic families,[138] modern Neopagans, followers of Spiritism, Theosophists and students of esoteric philosophies such as Kabbalah, and Gnostic and Esoteric Christianity as well as of Indian religions. Demographic survey data from 1999–2002 shows a significant minority of people from Europe and America, where there is reasonable freedom of thought and access to ideas but no outstanding recent reincarnationist tradition, believe we had a life before we were born, will survive death and be born again physically. The mean for the Nordic countries is 22%.[139] The belief in reincarnation is particularly high in the Baltic countries, with Lithuania having the highest figure for the whole of Europe, 44%. The lowest figure is in East Germany, 12%. In Russia, about one-third believes in reincarnation. The effect of communist anti-religious ideas on the beliefs of the populations of Eastern Europe seems to have been rather slight, if any, except apparently in East Germany.[139] Overall, 22% of respondents in Western Europe believe in reincarnation.[139] According to a 2005 Gallup poll 20 percent of U.S. adults believe in reincarnation. Recent surveys by the Barna Group, a Christian research nonprofit organization, have found that a quarter of U.S. Christians, including 10 percent of all born-again Christians, embrace the idea.[140]

Skeptic Carl Sagan asked the Dalai Lama what he would do if a fundamental tenet of his religion (reincarnation) were definitively disproved by science. The Dalai Lama answered, "If science can disprove reincarnation, Tibetan Buddhism would abandon reincarnation… but it's going to be mighty hard to disprove reincarnation."[141]

Ian Stevenson reported that belief in reincarnation is held (with variations in details) by adherents of almost all major religions except Christianity and Islam. In addition, between 20 and 30 percent of persons in western countries who may be nominal Christians also believe in reincarnation.[142]

One 1999 study by Walter and Waterhouse reviewed the previous data on the level of reincarnation belief and performed a set of thirty in-depth interviews in Britain among people who did not belong to a religion advocating reincarnation.[143] The authors reported that surveys have found about one fifth to one quarter of Europeans have some level of belief in reincarnation, with similar results found in the USA. In the interviewed group, the belief in the existence of this phenomenon appeared independent of their age, or the type of religion that these people belonged to, with most being Christians. The beliefs of this group also did not appear to contain any more than usual of "new age" ideas (broadly defined) and the authors interpreted their ideas on reincarnation as "one way of tackling issues of suffering", but noted that this seemed to have little effect on their private lives.

Waterhouse also published a detailed discussion of beliefs expressed in the interviews.[144] She noted that although most people "hold their belief in reincarnation quite lightly" and were unclear on the details of their ideas, personal experiences such as past-life memories and near-death experiences had influenced most believers, although only a few had direct experience of these phenomena. Waterhouse analyzed the influences of second-hand accounts of reincarnation, writing that most of the people in the survey had heard other people's accounts of past-lives from regression hypnosis and dreams and found these fascinating, feeling that there "must be something in it" if other people were having such experiences.

According to various Buddhist scriptures, Gautama Buddha believed in reincarnation and in the existence of other worlds of afterlife,

Since there actually is another world (any world other than the present human one, i.e. different rebirth realms), one who holds the view 'there is no other world' has wrong view...

Buddha also asserted that there is karma, which influences the rebirth, and that the cycles of repeated births and deaths are endless.[145][146] Before the birth of Buddha, ancient Indian scholars had developed competing theories of afterlife, including the materialistic school such as Charvaka,[147] which posited that death is the end, there is no afterlife, no soul, no rebirth, no karma, and they described death to be a state where a living being is completely annihilated, dissolved.[148] Buddha rejected this theory, adopted the alternate existing theories on rebirth, criticizing the materialistic schools that denied rebirth and karma, states Damien Keown.[149] Such beliefs are inappropriate and dangerous, stated Buddha, because such annihilationism views encourage moral irresponsibility and material hedonism;[150] he tied moral responsibility to rebirth.[145][149]

The Buddha introduced the concept that there is no permanent self (soul), and this central concept in Buddhism is called anattā.[151][152][153] Major contemporary Buddhist traditions such as Theravada, Mahayana and Vajrayana traditions accept the teachings of Buddha. These teachings assert there is rebirth, there is no permanent self and no irreducible ātman (soul) moving from life to another and tying these lives together, there is impermanence, that all compounded things such as living beings are aggregates dissolve at death, but every being reincarnates.[154][155][156] The rebirth cycles continue endlessly, states Buddhism, and it is a source of Dukkha (suffering, pain), but this reincarnation and Dukkha cycle can be stopped through nirvana. The anattā doctrine of Buddhism is a contrast to Hinduism, the latter asserting that "soul exists, it is involved in rebirth, and it is through this soul that everything is connected".[157][158][159]

Different traditions within Buddhism have offered different theories on what reincarnates and how reincarnation happens. One theory suggests that it occurs through consciousness (Pali: samvattanika-viññana)[160][161] or stream of consciousness (Pali: viññana-sotam,[162] Sanskrit: vijñāna-srotām, vijñāna-santāna, or citta-santāna) upon death, which reincarnates into a new aggregation. This process, states this theory, is similar to the flame of a dying candle lighting up another.[163][164] The consciousness in the newly born being is neither identical to nor entirely different from that in the deceased but the two form a causal continuum or stream in this Buddhist theory. Transmigration is influenced by a being's past karma (kamma).[165][166] The root cause of rebirth, states Buddhism, is the abiding of consciousness in ignorance (Pali: avijja, Sanskrit: avidya) about the nature of reality, and when this ignorance is uprooted, rebirth ceases.[167]

Buddhist traditions also vary in their mechanistic details on rebirth. Theravada Buddhists assert that rebirth is immediate while the Tibetan schools hold to the notion of a bardo (intermediate state) that can last up to forty-nine days.[168][169] The bardo rebirth concept of Tibetan Buddhism, along with Yidam, developed independently in Tibet without Indian influence, and involves forty two peaceful deities, and fifty eight wrathful deities.[170] These ideas led to mechanistic maps on karma and what form of rebirth one takes after death, discussed in texts such as The Tibetan Book of the Dead.[171][172] The major Buddhist traditions accept that the reincarnation of a being depends on the past karma and merit (demerit) accumulated, and that there are six realms of existence in which the rebirth may occur after each death.[173][16][57]

Within Japanese Zen, reincarnation is accepted by some, but rejected by others. A distinction can be drawn between "folk Zen", as in the Zen practiced by devotional lay people, and "philosophical Zen". Folk Zen generally accepts the various supernatural elements of Buddhism such as rebirth. Philosophical Zen, however, places more emphasis on the present moment.[174][175]

Some schools conclude that karma continues to exist and adhere to the person until it works out its consequences. For the Sautrantika school, each act "perfumes" the individual or "plants a seed" that later germinates. Tibetan Buddhism stresses the state of mind at the time of death. To die with a peaceful mind will stimulate a virtuous seed and a fortunate rebirth; a disturbed mind will stimulate a non-virtuous seed and an unfortunate rebirth.[176]

The body dies, assert the Hindu traditions, but not the soul, which they assume to be the eternal reality, indestructible and bliss.[177] Everything and all existence is believed to be connected and cyclical in Hinduism, all living beings composed of two things, the soul and the body or matter.[178]Atman does not change and cannot change by its innate nature in the Hindu belief.[178] In contrast, the body and personality, can change, constantly changes, is born and dies.[178] Current Karma impacts the future circumstances in this life, as well as the future forms and realms of lives.[179][180] Good intent and actions lead to good future, bad intent and actions lead to bad future, impacting how one reincarnates, in the Hindu view of existence.[181]

Hindus believe the self or soul (atman) repeatedly takes on a physical body, until moksha.

There is no permanent heaven or hell in Hinduism.[182] In the afterlife, based on one's karma, the soul is reborn as another being in heaven, hell, or a living being on earth (human, animal).[182] Gods too die once their past karmic merit runs out, as do those in hell, and they return getting another chance on earth. This reincarnation continues, endlessly in cycles, until one embarks on a spiritual pursuit, realizes self-knowledge, and thereby gains mokṣa, the final release out of the reincarnation cycles.[183] This release is believed to be a state of utter bliss, which Hindu traditions believe is either related or identical to Brahman, the unchanging reality that existed before the creation of universe, continues to exist, and shall exist after the universe ends.[184][185][186]

The Upanishads, part of the scriptures of the Hindu traditions, primarily focus on the liberation from reincarnation.[187][188][189] The Bhagavad Gita discusses various paths to liberation.[177] The Upanishads, states Harold Coward, offer a "very optimistic view regarding the perfectibility of human nature", and the goal of human effort in these texts is a continuous journey to self-perfection and self-knowledge so as to end Saṃsāra – the endless cycle of rebirth and redeath.[190] The aim of spiritual quest in the Upanishadic traditions is find the true self within and to know one's soul, a state that it believes leads to blissful state of freedom, moksha.[191]

Just as in the body childhood, adulthood and old age happen to an embodied being. So also he (the embodied being) acquires another body. The wise one is not deluded about this. – (2:13)[192]

As, after casting away worn out garments, a man later takes new ones. So after casting away worn out bodies, the embodied Self encounters other new ones. – (2:22)[193]

When an embodied being transcends, these three qualities which are the source of the body. Released from birth, death, old age and pain, he attains immortality. – (14:20)[194]

There are internal differences within Hindu traditions on reincarnation and the state of moksha. For example, the dualistic devotional traditions such as Madhvacharya's Dvaita Vedanta tradition of Hinduism champion a theistic premise, assert that human soul and Brahman are different, loving devotion to Brahman (god Vishnu in Madhvacharya's theology) is the means to release from Samsara, it is the grace of God which leads to moksha, and spiritual liberation is achievable only in after-life (videhamukti).[195] The nondualistic traditions such as Adi Shankara's Advaita Vedanta tradition of Hinduism champion a monistic premise, asserting that the individual human soul and Brahman are identical, only ignorance, impulsiveness and inertia leads to suffering through Saṃsāra, in reality they are no dualities, meditation and self-knowledge is the path to liberation, the realization that one's soul is identical to Brahman is moksha, and spiritual liberation is achievable in this life (jivanmukti).[196][197]

In Jainism, the reincarnation doctrine, along with its theories of Saṃsāra and Karma, are central to its theological foundations, as evidenced by the extensive literature on it in the major sects of Jainism, and their pioneering ideas on these topics from the earliest times of the Jaina tradition.[43][44] Reincarnation in contemporary Jainism traditions is the belief that the worldly life is characterized by continuous rebirths and suffering in various realms of existence.[45][44][198]

Karma forms a central and fundamental part of Jain faith, being intricately connected to other of its philosophical concepts like transmigration, reincarnation, liberation, non-violence (ahiṃsā) and non-attachment, among others. Actions are seen to have consequences: some immediate, some delayed, even into future incarnations. So the doctrine of karma is not considered simply in relation to one life-time, but also in relation to both future incarnations and past lives.[199]Uttarādhyayana-sūtra 3.3–4 states: "The jīva or the soul is sometimes born in the world of gods, sometimes in hell. Sometimes it acquires the body of a demon; all this happens on account of its karma. This jīva sometimes takes birth as a worm, as an insect or as an ant."[200] The text further states (32.7): "Karma is the root of birth and death. The souls bound by karma go round and round in the cycle of existence."[200]

Actions and emotions in the current lifetime affect future incarnations depending on the nature of the particular karma. For example, a good and virtuous life indicates a latent desire to experience good and virtuous themes of life. Therefore, such a person attracts karma that ensures that his future births will allow him to experience and manifest his virtues and good feelings unhindered.[201] In this case, he may take birth in heaven or in a prosperous and virtuous human family. On the other hand, a person who has indulged in immoral deeds, or with a cruel disposition, indicates a latent desire to experience cruel themes of life.[202] As a natural consequence, he will attract karma which will ensure that he is reincarnated in hell, or in lower life forms, to enable his soul to experience the cruel themes of life.[202]

There is no retribution, judgment or reward involved but a natural consequences of the choices in life made either knowingly or unknowingly. Hence, whatever suffering or pleasure that a soul may be experiencing in its present life is on account of choices that it has made in the past.[203] As a result of this doctrine, Jainism attributes supreme importance to pure thinking and moral behavior.[204]

The Jain texts postulate four gatis, that is states-of-existence or birth-categories, within which the soul transmigrates. The four gatis are: deva (demi-gods), manuṣya (humans), nāraki (hell beings) and tiryañca (animals, plants and micro-organisms).[205] The four gatis have four corresponding realms or habitation levels in the vertically tiered Jain universe: demi-gods occupy the higher levels where the heavens are situated; humans, plants and animals occupy the middle levels; and hellish beings occupy the lower levels where seven hells are situated.[205]

Single-sensed souls, however, called nigoda,[206] and element-bodied souls pervade all tiers of this universe. Nigodas are souls at the bottom end of the existential hierarchy. They are so tiny and undifferentiated, that they lack even individual bodies, living in colonies. According to Jain texts, this infinity of nigodas can also be found in plant tissues, root vegetables and animal bodies.[207] Depending on its karma, a soul transmigrates and reincarnates within the scope of this cosmology of destinies. The four main destinies are further divided into sub-categories and still smaller sub-sub-categories. In all, Jain texts speak of a cycle of 8.4 million birth destinies in which souls find themselves again and again as they cycle within samsara.[208]

In Jainism, God has no role to play in an individual's destiny; one's personal destiny is not seen as a consequence of any system of reward or punishment, but rather as a result of its own personal karma. A text from a volume of the ancient Jain canon, Bhagvati sūtra 8.9.9, links specific states of existence to specific karmas. Violent deeds, killing of creatures having five sense organs, eating fish, and so on, lead to rebirth in hell. Deception, fraud and falsehood lead to rebirth in the animal and vegetable world. Kindness, compassion and humble character result in human birth; while austerities and the making and keeping of vows lead to rebirth in heaven.[209]

Each soul is thus responsible for its own predicament, as well as its own salvation. Accumulated karma represent a sum total of all unfulfilled desires, attachments and aspirations of a soul.[210][211] It enables the soul to experience the various themes of the lives that it desires to experience.[210] Hence a soul may transmigrate from one life form to another for countless of years, taking with it the karma that it has earned, until it finds conditions that bring about the required fruits. In certain philosophies, heavens and hells are often viewed as places for eternal salvation or eternal damnation for good and bad deeds. But according to Jainism, such places, including the earth are simply the places which allow the soul to experience its unfulfilled karma.[212]

Founded in the 15th century, Sikhism's founder Guru Nanak had a choice between the cyclical reincarnation concept of ancient Indian religions and the linear concept of early 7th-century Islam, and he chose the cyclical concept of time.[213][214] Sikhism teaches reincarnation theory similar to those in Hinduism, but with some differences from its traditional doctrines.[215] Sikh rebirth theories about the nature of existence are similar to ideas that developed during the devotional Bhakti movement particularly within some Vaishnavism traditions, which define liberation as a state of union with God attained through the grace of God.[216][217][218]

The doctrines of Sikhism teach that the soul exists, and is passed from one body to another in endless cycles of Saṃsāra, until liberation. Each birth begins karma (karam), these actions leave a karni (karmic signature) on one's soul which influences rebirth states Sikhism, but it is God whose grace that liberates.[215] The way out of the reincarnation cycle, asserts Sikhism, is to live an ethical life, devote oneself to God and constantly remember God's name.[215] The precepts of Sikhism encourage the bhakti of One Lord for mukti (liberation).[215][219]

The Yoruba believe in reincarnation within the family. The names Babatunde (Father returns), Yetunde (Mother returns), Babatunji (Father wakes once again) and Sotunde (The wise man returns) all offer vivid evidence of the Ifa concept of familial or lineal rebirth. There is no simple guarantee that your grandfather or great uncle will "come back" in the birth of your child, however.

Whenever the time arrives for a spirit to return to Earth (otherwise known as The Marketplace) through the conception of a new life in the direct bloodline of the family, one of the component entities of a person's being returns, while the other remains in Heaven (Ikole Orun). The spirit that returns does so in the form of a Guardian Ori. One's Guardian Ori, which is represented and contained in the crown of the head, represents not only the spirit and energy of one's previous blood relative, but the accumulated wisdom he or she has acquired through a myriad of lifetimes. This is not to be confused with one’s spiritual Ori, which contains personal destiny, but instead refers to the coming back to The Marketplace of one's personal blood Ori through one's new life and experiences.

Jewish mystical texts (the Kabbalah), from their classic Medieval canon onwards, teach a belief in Gilgul Neshamot (Hebrew for metempsychosis of souls: literally "soul cycle", plural "gilgulim"). It is a common belief in contemporary Hasidic Judaism, which regards the Kabbalah as sacred and authoritative, though unstressed in favour of a more innate psychological mysticism. Kabbalah also teaches that "The soul of Moses is reincarnated in every generation."[220] Other, Non-Hasidic, Orthodox Jewish groups while not placing a heavy emphasis on reincarnation, do acknowledge it as a valid teaching.[221] Its popularisation entered modern secular Yiddish literature and folk motif.

The 16th century mystical renaissance in communal Safed replaced scholastic Rationalism as mainstream traditional Jewish theology, both in scholarly circles and in the popular imagination. References to gilgul in former Kabbalah became systemised as part of the metaphysical purpose of creation. Isaac Luria (the Ari) brought the issue to the centre of his new mystical articulation, for the first time, and advocated identification of the reincarnations of historic Jewish figures that were compiled by Haim Vital in his Shaar HaGilgulim.[222]Gilgul is contrasted with the other processes in Kabbalah of Ibbur ("pregnancy"), the attachment of a second soul to an individual for (or by) good means, and Dybuk ("possession"), the attachment of a spirit, demon, etc. to an individual for (or by) "bad" means.

In Lurianic Kabbalah, reincarnation is not retributive or fatalistic, but an expression of Divine compassion, the microcosm of the doctrine of cosmic rectification of creation. Gilgul is a heavenly agreement with the individual soul, conditional upon circumstances. Luria's radical system focused on rectification of the Divine soul, played out through Creation. The true essence of anything is the divine spark within that gives it existence. Even a stone or leaf possesses such a soul that "came into this world to receive a rectification". A human soul may occasionally be exiled into lower inanimate, vegetative or animal creations. The most basic component of the soul, the nefesh, must leave at the cessation of blood production. There are four other soul components and different nations of the world possess different forms of souls with different purposes. Each Jewish soul is reincarnated in order to fulfil each of the 613 Mosaic commandments that elevate a particular spark of holiness associated with each commandment. Once all the Sparks are redeemed to their spiritual source, the Messianic Era begins. Non-Jewish observance of the 7 Laws of Noah assists the Jewish people, though Biblical adversaries of Israel reincarnate to oppose.

The following is a story of human-to-human reincarnation as told by Thunder Cloud, a Winnebago (Ho-Chunk tribe) shaman referred to as T. C. in the narrative. Here T. C. talks about his two previous lives and how he died and came back again to this his third lifetime. He describes his time between lives, when he was “blessed” by Earth Maker and all the abiding spirits and given special powers, including the ability to heal the sick.

T. C.'s Account of His Two Reincarnations:

I (my ghost) was taken to the place where the sun sets (the west). ... While at that place, I thought I would come back to earth again, and the old man with whom I was staying said to me, “My son, did you not speak about wanting to go to the earth again?” I had, as a matter of fact, only thought of it, yet he knew what I wanted. Then he said to me, “You can go, but you must ask the chief first.” Then I went and told the chief of the village of my desire, and he said to me, “You may go and obtain your revenge upon the people who killed your relatives and you.” Then I was brought down to earth. ... There I lived until I died of old age. ... As I was lying [in my grave], someone said to me, “Come, let us go away.” So then we went toward the setting of the sun. There we came to a village where we met all the dead. ... From that place I came to this earth again for the third time, and here I am.[225] (Radin, 1923)

Though the major Christian denominations reject the concept of reincarnation, a large number of Christians profess the belief. In a survey by the Pew Forum in 2009, 24% of American Christians expressed a belief in reincarnation.[226] In a 1981 Survey in Europe 31% of regular churchgoing Catholics expressed a belief in reincarnation.[227]

Geddes MacGregor, an Episcopalian priest and professor of Philosophy, makes a case for the compatibility of Christian doctrine and reincarnation.[228]

There is evidence[229][230] that the writing of Origen, a Church father in early Christian times, was mistranslated into Latin due to religious bias and that he taught reincarnation in his lifetime. One of the epistles written by St. Jerome, "To Avitus" (Letter 124 ; Ad Avitum. Epistula CXXIV),[231] asserts that Origen's On First Principles (Latin: De Principiis; Greek: Περὶ Ἀρχῶν[232]) was mistranscribed from Greek into Latin:

About ten years ago that saintly man Pammachius sent me a copy of a certain person's [ Rufinus's[231] ] rendering, or rather misrendering, of Origen's First Principles; with a request that in a Latin version I should give the true sense of the Greek and should set down the writer's words for good or for evil without bias in either direction. When I did as he wished and sent him the book, he was shocked to read it and locked it up in his desk lest being circulated it might wound the souls of many.[230]

Under the impression that Origen was a heretic like Arius, St. Jerome criticizes ideas described in On First Principles. Further in "To Avitus" (Letter 124), St. Jerome writes about "convincing proof" that Origen teaches reincarnation in the original version of the book:

The following passage is a convincing proof that he holds the transmigration of the souls and annihilation of bodies. 'If it can be shown that an incorporeal and reasonable being has life in itself independently of the body and that it is worse off in the body than out of it; then beyond a doubt bodies are only of secondary importance and arise from time to time to meet the varying conditions of reasonable creatures. Those who require bodies are clothed with them, and contrariwise, when fallen souls have lifted themselves up to better things, their bodies are once more annihilated. They are thus ever vanishing and ever reappearing.'[230]

The original text of On First Principles has almost completely disappeared. It remains extant as De Principiis in fragments faithfully translated into Latin by St. Jerome and in "the not very reliable Latin translation of Rufinus."[232]

Islamic scriptures reject any idea of reincarnation of human beings or God.[233][234][235] It teaches a linear concept of life, wherein a human being has only one life and upon death is judged by God, then rewarded to heaven or punished in hell.[233][236] Islam teaches final resurrection and Judgement Day,[234] but there is no prospect of reincarnation of a human being into a different body or being.[233] During the early history of Islam, some of the Caliphs persecuted to the point of extinction all reincarnation-believing people (Manichaeism) in Mesopotamia and Persia (modern day Iraq and Iran).[234] However, some Muslim minority sects such as those found among Sufis, and some Muslims in South Asia and Indonesia have retained their pre-Islamic Hindu and Buddhist beliefs in reincarnation.[234]

The idea of reincarnation is accepted by a few Muslim sects, particularly of the Ghulat,[237] and by other sects in the Muslim world. Historically, South Asian Isma'ilis performed chantas yearly, one of which is for seeking forgiveness of sins committed in past lives. Alawis belonging to Shia denomination of Islam hold that they were originally stars or divine lights that were cast out of heaven through disobedience and must undergo repeated reincarnation (or metempsychosis) before returning to heaven.[238] They can be reincarnated as Christians or others through sin and as animals if they become infidels.[239]

Reincarnation was also accepted by some streams of Sufism. Modern Sufis who embrace the idea include Bawa Muhaiyadeen.[240] However Hazrat Inayat Khan has criticized the idea as unhelpful to the spiritual seeker.[241]

Reincarnation is a paramount tenet in the Druze faith.[242] There is an eternal duality of the body and the soul and it is impossible for the soul to exist without the body. Therefore, reincarnations occur instantly at one's death. While in the Hindu and Buddhist belief system a soul can be transmitted to any living creature, in the Druze belief system this is not possible and a human soul will only transfer to a human body. Furthermore, a male Druze can only be reincarnated as another male Druze and a female Druze can only be reincarnated as another female Druze. Additionally, souls cannot be divided and the number of souls existing is finite.[243]

Very few Druzes are able to recall their past but, if they are able to they are called a Nateq. Typically souls who have died violent deaths in their previous incarnation will be able to recall memories. Since death is seen as a quick transient state, mourning is discouraged.[243] Unlike other Abrahamic faiths, heaven and hell are spiritual. Heaven is the ultimate happiness received when soul escapes the cycle of rebirths and reunites with the Creator. While hell is conceptualized the bitterness of being unable to reunite with the Creator and escape from the cycle of rebirth.[244]

The Theosophical Society draws much of its inspiration from India. The idea is, according to a recent Theosophical writer, "the master-key to modern problems", including heredity.[245] In the Theosophical world-view reincarnation is the vast rhythmic process by which the soul, the part of a person which belongs to the formless non-material and timeless worlds, unfolds its spiritual powers in the world and comes to know itself. It descends from sublime, free, spiritual realms and gathers experience through its effort to express itself in the world. Afterwards there is a withdrawal from the physical plane to successively higher levels of reality, in death, a purification and assimilation of the past life. Having cast off all instruments of personal experience it stands again in its spiritual and formless nature, ready to begin its next rhythmic manifestation, every lifetime bringing it closer to complete self-knowledge and self-expression. However it may attract old mental, emotional, and energetic karma patterns to form the new personality.

Anthroposophy describes reincarnation from the point of view of Western philosophy and culture. The ego is believed to transmute transient soul experiences into universals that form the basis for an individuality that can endure after death. These universals include ideas, which are intersubjective and thus transcend the purely personal (spiritual consciousness), intentionally formed human character (spiritual life), and becoming a fully conscious human being (spiritual humanity). Rudolf Steiner described both the general principles he believed to be operative in reincarnation, such as that one's will activity in one life forms the basis for the thinking of the next,[248] and a number of successive lives of various individualities.[249]

Awareness of past lives, dreams, and soul travel are spiritual disciplines practiced by students of Eckankar. Eckankar teaches that each person is Soul, which transcends time and space. Soul travel is a term specific to Eckankar that refers to a shift in consciousness. Eckists believe the purpose of being aware of past lives is to help with understanding personal conditions in the present. Practicing students of Eckankar can become aware of past lives, through dreams, soul travel, and spiritual exercises called contemplations. This form of contemplation is the active, unconditional practice of going within to connect with the "Light and Sound of God" known as the divine life current or Holy Spirit.

Past reincarnation, usually termed "past lives", is a key part of the principles and practices of the Church of Scientology. Scientologists believe that the human individual is actually a thetan, an immortal spiritual entity, that has fallen into a degraded state as a result of past-life experiences. Scientology auditing is intended to free the person of these past-life traumas and recover past-life memory, leading to a higher state of spiritual awareness. This idea is echoed in their highest fraternal religious order, the Sea Organization, whose motto is "Revenimus" or "We Come Back", and whose members sign a "billion-year contract" as a sign of commitment to that ideal. L. Ron Hubbard, the founder of Scientology, does not use the word "reincarnation" to describe its beliefs, noting that: "The common definition of reincarnation has been altered from its original meaning. The word has come to mean 'to be born again in different life forms' whereas its actual definition is 'to be born again into the flesh of another body.' Scientology ascribes to this latter, original definition of reincarnation."[250]

The first writings in Scientology regarding past lives date from around 1951 and slightly earlier. In 1960, Hubbard published a book on past lives entitled Have You Lived Before This Life. In 1968 he wrote Mission into Time, a report on a five-week sailing expedition to Sardinia, Sicily and Carthage to see if specific evidence could be found to substantiate L. Ron Hubbard's recall of incidents in his own past, centuries ago.

The Indian spiritual teacher Meher Baba stated that reincarnation occurs due to desires and once those desires are extinguished the ego-mind ceases to reincarnate:

The power that keeps the individual soul bound to the wheel of life and death is its thirst for separate existence, which is a condition for a host of cravings connected with objects and experiences of the world of duality. It is for the fulfillment of cravings that the ego-mind keeps on incarnating itself. When all forms of craving disappear, the impressions which create and enliven the ego-mind disappear. With the disappearance of these impressions, the ego-mind itself is shed with the result that there is only the realisation of the one eternal, unchanging Oversoul or God, Who is the only reality. God-realisation is the end of the incarnations of the ego-mind because it is the end of its very existence. As long as the ego-mind exists in some form, there is an inevitable and irresistible urge for incarnations. When there is cessation of the ego-mind, there is cessation of incarnations in the final fulfillment of Self-realisation.[251] (1967)

Tomb of Allan Kardec, founder of spiritism. The inscription says in French "To be born, die, again be reborn, and so progress unceasingly, such is the law".

Spiritism is a Christian philosophy codified in the 19th century by the French educator Allan Kardec. Spiritism soon spread to other countries, having today 35 countries represented in the International Spiritist Council. In countries like Brazil the movement had spread and became widely accepted, mostly due to Chico Xavier's works. Today the official spiritist community has about 20 million adepts, though due to local syncretism, it is accepted and somehow practiced by three times as many across the country. Some statistics even mention an adherence to Spiritist practices by 40 million people in Brazil.

Spiritism teaches reincarnation or rebirth into human life after death. This basically distinguishes Spiritism from Spiritualism. According to the Spiritist doctrine, reincarnation explains the moral and intellectual differences among men. It also provides the path to man's moral and intellectual perfection by amending for his mistakes and increasing his knowledge in successive lives. For this reason Spiritism does not accept rebirth in animals as this would be retrogressive. Reincarnation is the natural method of the perfection process through which the Spirit faces countless different situations, problems and obstacles, and needs to learn how to deal with them. The central tenet of Spiritist doctrine is the belief in spiritual life. The spirit is eternal, and evolves through a series of incarnations in the material world. The true life is the spiritual one; life in the material world is just a short-termed stage, where the spirit has the opportunity to learn and develop its potentials. Reincarnation is the process where the spirit, once free in the spiritual world, comes back to the world for further learning.

Wicca is a neo-pagan religion focused on nature, guided by the philosophy of Wiccan Rede that advocates Harm None, Do As Ye Will. The concept of karmic return in Wicca states that our deeds return to us threefold, or multiple times to teach us lessons (The Threefold Law), whether in this lifetime or the next. Reincarnation therefore is an accepted part of the Wiccan faith.[252] Wiccans also believe in death and afterlife as important experiences for the soul to transform and prepare for future lifetimes.

^The book Reincarnation in Christianity, by the theosophist Geddes MacGregor (1978) asserted that Origen believed in reincarnation. MacGregor is convinced that Origen believed in and taught about reincarnation but that his texts written about the subject have been destroyed. He admits that there is no extant proof for that position. The allegation was also repeated by Shirley MacLaine in her book Out On a Limb. Origen does discuss the concept of transmigration (metensomatosis) from Greek philosophy, but it is repeatedly stated that this concept is not a part of the Christian teaching or scripture in his Comment on the Gospel of Matthew (which survives only in a 6th-century Latin translatio): "In this place [when Jesus said Elijah was come and referred to John the Baptist] it does not appear to me that by Elijah the soul is spoken of, lest I fall into the doctrine of transmigration, which is foreign to the Church of God, and not handed down by the apostles, nor anywhere set forth in the scriptures" (13:1:46–53, see Commentary on Matthew, Book XIII
